Definitions
- the present invention relates to the technology of high-temperature components for thermal machines, especially for gas turbines. It refers to a high temperature thermal barrier coating according to the preamble of claim 1.
- TBCs Thermal Barrier Coatings
- YSZ Yttria Stabilized Zirconia
- An increase of operating temperature can be obtained by either incorporating new stabilizing elements to zirconia or by using new protection materials.
- the goal is a new generation of gas turbines which require TBCs being able to withstand temperatures around 1400 °C during more than 20'000 hours. These high operating temperatures require new coating solutions.
- HT-TBC high-temperature thermal barrier coating
- TC thermal conductivity
- the high temperature thermal barrier coating for the protection of thermally loaded components of a thermal machine, especially a gas turbine consists of a stabilized ZrO 2 composition. It is characterized in that said composition is stabilized with at least 15 mol% Y 1+ ⁇ Ta 1- ⁇ O 4- ⁇ , the ZrO 2 is partially substituted by at least 10 mol% HfO 2 and the composition is established according to the formula Y 1 + v ⁇ Ta 1 - v ⁇ O 4 - v z ⁇ Zr 1 - x ⁇ Hf x ⁇ O 2 1 - z , with x ranging from 0.1 to 0.5, ⁇ ranging from -0.1 to 0.2 and z ranging from 0.15 to 0.25.
- x will range from 0.15 to 0.25
- v will range from 0 to 0.1
- z will range from 0.18 to 0.23.
- the high temperature thermal barrier coating covers a component made of a base alloy.
- a bondcoat is provided between the base alloy of the component and the high temperature thermal barrier coating.
- an intermediate layer is provided between the bondcoat and the high temperature thermal barrier coating.
- the intermediate layer consists of 7YSZ deposited by a thermal spray process.
- the high temperature thermal barrier coating is deposited by a thermal spray process.
- the invention is intended at providing a thermal barrier coating material and system thermodynamically stable at temperatures up to >1400°C.
- the material is a tetragonal stabilized material which is stable at high temperature and has a high toughness value.
- Most of the high temperature stable zirconia have a cubic structure not allowing them to have a high toughness due to the absence of ferroelasticity in the cubic system.
- Thermal barrier coating systems made of 6-8 wt% Y 2 O 3 stabilized ZrO 2 (7YSZ) are not suited for use at temperatures above 1300°C due to the decomposition of the metastable tetragonal phase into cubic, and low Y 2 O 3 content zirconia which transforms into monoclinic upon cooling. The monoclinic to tetragonal transformation leads to a volume change and will thus reduce the life of the coating.
- Fully stabilized zirconia systems have been considered as TBC material, but they have not the high toughness that has tetragonal 7YSZ, due to the absence of a ferroelastic mechanism. For this reason a stable tetragonal zirconia composition is highly desirable.
- ZrO 2 stabilized with YTaO 4 has been proposed as a TBC material having a tetragonal unit cell and being stable at high temperature.
- the present invention proposes a ZrO 2 composition stabilized with YTaO 4 where ZrO 2 is partially substituted by HfO 2 , bringing two advantages:
- the HT-TBC of the invention can be applied as a single layer ceramic layer directly on the bondcoat (see Fig. 2 ), or as a dual layer system where 7YSZ is deposited as an intermediate layer on the bondcoat and the new HT-TBC material is deposited on the 7YSZ layer (see Fig. 3 ).
- High temperature annealing of the proposed material composition shows no decomposition at 1500°C after 4 hours of annealing, a condition where a 7YSZ system will be fully decomposed.
- Fig. 2 shows a section of a component according to an embodiment of the invention, the component 10 being made of a base alloy 11, which is covered by a bondcoat 12, the bondcoat 12 being directly covered by a HT-TBC 13 according to the invention.
- Fig. 3 shows a section of a component according to another embodiment of the invention, the component 10' being made of a base alloy 11, which is covered by a bondcoat 12, the bondcoat 12 being covered by a HT-TBC 13 according to the invention with an intermediate layer 14 being provided between the bondcoat 12 and the HT-TBC 13.
- the TaYSZH system has the following compositions:
- Synthesis is done by reverse co-precipitation with NH 4 OH as precipitating agent.
